This volume contains a selection of papers on grammaticalization from a broad perspective. Some of the papers focus on basic concepts in grammaticalization research such as the concept of 'grammar' as the endpoint of grammaticalization processes, erosion, (uni)directionality, the relation between grammaticalization and constructions, subjectification, and the relation between grammaticalization and analogy. Other papers shed a critical light on grammaticalization as an explanatory parameter in language change. New case studies of micro-processes of grammaticalization complete the selection. The empirical evidence for (and against) grammaticalization comes from diverse domains: subject control, clitics, reciprocal markers, pronouns and agreement markers, gender markers, auxiliaries, aspectual categories, intensifying adjectives and determiners, and pragmatic markers. The languages covered include English and its varieties, German, Dutch, Italian, Spanish, French, Slavonic languages, and Turkish. The book will be valuable to scholars working on grammaticalization and language change as well as to those interested in individual languages.

Grammaticalization theory has played a major role in the developments in language typology and functional linguistics during the last three decades. Grammaticalization phenomena show that grammars evolve in a continuous way following cross-linguistically established diachronic paths. The contributions in this book shed new light on some central issues in grammaticalization theory such as the (uni-)directionality debate, the relation between grammaticalization and constructions, and the concept of multiple grammaticalization. Evidence for grammaticalization in several domains of grammar is presented: adpositions, numeral classifiers, honorifics, agreement markers, applicatives, reciprocals, delexical verbs, auxiliaries, relative clauses, and discourse particles. The empirical investigations come from several languages, among them many understudied languages such as Nanafwe, Maltese, Manambu, Chibchan and Siouan languages.

Grammaticalization has often been described as a gradual phenomenon. While many studies have discussed the quantitative aspects of grammaticalization, there has been little to no work that has tried to propose a way of measuring degrees of grammaticalization. This book addresses this gap by proposing a corpus-based approach to the measurement of grammaticalization, using binary logistic regression modelling. Such an approach has theoretical benefits as it can provide empirical evidence for the gradience and gradualness of grammaticalization. It can help substantiate observations that have been done on the basis of case studies so far, such as the hypothesized unidirectionality of grammaticalization. In addition, as the methods proposed in this book rely on corpus-based data only, it offers a way of comparing grammaticalization across multiple languages, which is currently a challenging endeavour. What this book hopes to achieve is to start a discussion on the measurement of grammaticalization. To draw a parallel, the field of morphological productivity has greatly benefited from the discussions (and disputes) regarding how its object of study should be measured, and I believe that so will the field of grammaticalization.

This book presents a critical assessment of research on grammaticalization, a central element in the process by which grammars are created. Leading scholars discuss its core theoretical and methodological bases, report on work in the field, and point to directions for new research. They represent every relevant theoretical perspective and approach.

Grammaticalization research looks back on a rich history, but recent empirical findings, as well as new insights from cognitive science and psycholinguistics, entice researchers to reassess and review what we know about the process. This book presents a detailed study of the grammaticalization of motion verbs in the Mayan languages. The focus lies on variation in the parallel grammaticalization of motion verbs into auxiliaries and directionals. It is demonstrated that the genetically related and areally close languages do not always grammaticalize source items in the same way - both from a formal and meaning perspective. The empirical findings suggest that traditional theories on grammaticalization do not capture the complex nature of the phenomenon entirely. Therefore, a Network Approach to grammaticalization is introduced which emphasizes a 'meaning-first' account. The approach seeks to combine the conceptual with the discourse-pragmatic while being firmly grounded in cognitive and psychological facts. New insights into the grammaticalization behavior of the world's languages are offered, while well-established notions and assumptions within the grammaticalization research paradigm are reviewed and challenged.

"Thoughts on grammaticalization" was first published in a working-paper version in 1982 and became very influential immediately, even though it was properly published only in 1995. Despite its modest title, the book can be read as an advanced introduction to grammaticalization, though its conception is very original. The present edition contains a number of corrections of the 1995 edition. After a short review of the history of research, the work introduces and delimits the concepts related to grammaticalization. It then provides extensive exemplification of grammaticalization phenomena in diverse languages, ordered by grammatical domains such as the verbal, pronominal and nominal sphere and clause level relations. The final chapter presents a theory of grammaticalization which is based on the autonomy of the linguistic sign with respect to the paradigmatic and syntagmatic axes. This is the basis of the structural parameters that constitute grammaticalization. They are operationalized to the point of rendering degrees of grammaticalization measurable.

The volume contains a selection of papers originally presented at the symposium on “Areal patterns of grammaticalization and cross-linguistic variation in grammaticalization scenarios” held on 12-14 March 2015 at Johannes Gutenberg University of Mainz. The papers, written by leading scholars combining expertise in historical linguistics and grammaticalization research, study variation in grammaticalization scenarios in a variety of language families (Slavic, Indo-Aryan, Tibeto-Burman, Bantu, Mande, "Khoisan", Siouan, and Mayan). The volume stands out in the vast literature on grammaticalization by focusing on variation in grammaticalization scenarios and areal patterns in grammaticalization. Apart from documenting new grammaticalization paths, the volume makes a methodological contribution as it addresses an important question of how to reconcile universal outcomes of grammaticalization processes with the fact that the input to these processes is language-specific and construction-specific.
